Witchblade - Season 2 Episode 11

Jake and Danny go undercover posing as hot-headed fighters to investigate the murder of a young man who was in an underground bare-knuckle fight club. But the deadly game becomes complicated when Sara's long-lost love, Conchobar, steps into the ring. In a bizarre twist of fate, Sara finds herself falling in love with him (despite having never met him before in this alternate reality) and thus risks everything (including the Witchblade) to save her lover and bring the killer to justice.
